A community space for OpenMQTTgateway discussions


With the increase of OpenMQTTgateway users the current community ecosystem composed of github + a gitter chat is showing its limits, especially for the chat which doesn't enable to structure discussions around a subject. 

So as to have more capitalisation on the questions, answers and informations coming from the community I'm introducing a forum based on discourse

Giving the opportunity to build together a knowledge base around OpenMQTTGateway.





Hope you enjoy it, don't hesitate to post questions and share your thoughts, ideas or information around OpenMQTTGateway.

433toMQTTto433 - Bidirectional ESP8266 NodeMCU gateway between RF 433Mhz signal and MQTT

The goal  is to act as a gateway between 433Mhz sensors and a MQTT broker or between the MQTT broker and 433Mhz actuators, It enables to:
receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data publish MQTT data to a different topic related to received 433Mhz signal 
It can be an interesting part in an home automation system so as to interface sensors and actuators (wall sockets) with software like openhab.

The interest of putting this gateway to an ESP8266 and not on a raspberry pi is to be able to manage security actions at gateway level (power on a siren, cut power to certain devices) following RF data received by sensors without being dependent to the PI for security related actions.

Infrared IR, 433mhz and MQTT on ESP8266 bidirectional gateway OpenMQTTGateway

Following discussions on the home assistant forum people gave me the idea to add Infrared communication to the 433mhz gateway. 

The goal is to act as a gateway between 433Mhz sensors, infrared remote controls and a MQTT broker or between the MQTT broker and 433Mhz actuators, infrared devices, It enables to:
receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data publish MQTT data to a different topic related to received 433Mhz signal receive MQTT data from a topic and send infrared signal corresponding to the received MQTT data publish MQTT data to a different topic related to received infrared signal 
It can be an interesting part in an home automation system so as to interface sensors and actuators (wall sockets), your tv, home cinema, hifi ... with software like openhab or home assistant.

SONOFF RF BRIDGE with custom firmware

From an user request I took a look into the RF SONOFF Bridge, a quite interesting device from SONOFF. It is able to send and receive 433mhz signal with a very competitive price of less than 10€.

I already own several SONOFF Smart switches on which I loaded custom firmwares with success. One is working since months perfectly!

Here is how the RF bridge looks inside:




First thing I used to do when I launch some new development is to check the state of the art, as we often say google is your friend. And by searching the compatibility between the bridge and RCSwitch library (the main RF library of OpenMQTTGateway) I fall into the very good work of Xose Pérez (Tinkerman)
http://tinkerman.cat/hacking-sonoff-rf-bridge-433/
He ported successfully its ESPURNA code to the Sonoff RF Bridge.

After following its instructions and some mistakes from me (be careful about choosing the good line of pins on the bridge for your FTDI connectors :-( and choose the following parameters except the port) I successful…
